    I totally agree with the judges. Absolutely breathtaking videos *thumbs up*

    The five movies are available on DVD but you can watch them online as well:

    Very interesting videos. Plus, there's a guidebook (39MB pdf file) with full-color images, diagrams, and charts that will make the science of heliophysics clear for all readers. You can download it (see the link above).

    well deserved bump:

    Here's another interesting video which has got to do with Earth and Sun.



    This 4 min video tells us about hidden portals in Earth's magnetic field :)
    They're called X-points or electron diffusion regions. :cool:

    A huge, dark-colored filament stretched across nearly half the solar face (800000 km in length) on August 5th. Here's the hires image:

    And now here's some info about solar flares. According to James R. Webb, astronomy professor in the Department of Physics, solar flares are a pretty common occurrence, typically occurring in cycles. The current cycle is expected to peak in 2013.

    Here's the video :)

    That's a very spectacular scene because Coronal Mass Ejections (CME) are sexy.



    This video is gonna make me come .... over to that place.

    Jesus man, I love how progressive the science community has become recently. First Curiosity, now this. My only hope is that the pace will hold on and speed up, so we can reach some great new technological achievements before we blow ourselves up.

    By the way, nobody fucks with the Sun. Watch Sunshine.

    Another series of CMEs (coronal mass ejections) appeared on August 20. This bulbous CME certainly resembled a light bulb.

    Here's the video:

    That CME is huge. It starts off a good fraction of the size of the sun and then grows much larger than the sun. Awesome.

    And the sun is 800,000 miles across. Now stick that in yer pipe and smoke it!

    Yup they said the inner solar corona is 5.25 million miles away from the Sun.

    Another eruption on the Sun on August 31.

    Here are two spectacular videos. One of them in HD



    Mindblowing ...

    That cycle you spoke of earlier is ca 11 years btw. I remember the last one' they had some troubles in canada i think because of it.

    Another spectacular video showing how prominence erupted off the surface of the Sun around 19:00 UT on August 31, 2012 and just kept going. This video from the STEREO Behind spacecraft shows the prominence and the coronal mass ejection (CME) in which its is embedded as it leaves the Sun (orange, EUVI) and travels through the fields of view of COR1 (green), COR2 (red), and HI1 (blue) telescopes before it finally disappears from HI1 around the end of September 2, still clearly visible more than two days after it erupted.



    It's the eruption which was posted 2 posts above.

    It is difficult to comprehend the size of earth compared to these explosions.

    After reading the title, I couldn't help thinking of MoTS: Mysteries of the Sith.

    That's pretty cool, but, CMEs happen all the time, shooting out in all directions.
    Let's hope there's no strong X-class solar event + CME that ends up making a direct hit on the Earth though.

    Another CME. Happened today (October 5). This time it's headed exactly towards Earth. Will get here in 3 days or something lol

    Not a very strong one though.
    A strong X class flare would be thousands of times more intense.

    Coronal Hole & Loops

    Using a gradient filter on imagery captured by NASA's Solar Dynamics Observatory (SDO) helped create this stunning video :)




    And this is the image of a coronal hole on the sun:

    Fascinating!

    Sun just sent another Filament Eruption & CME. Now it's Earth-directed :p

    NASA's 3-minute solar cycle primer

    A very interesting and informative video about solar flares, coronal mass ejections (CMEs), and flipping poles

    What is a Solar X-Flare?: Sun's 'Richter Scale' Explained | Video



    The video below shows coronal loops on the Sun during January 5 through 7 – the arcs extending off of the Sun where plasma moves along the magnetic field lines. The brightest spots seen here are locations where the magnetic field near the surface is exceptionally strong. The characteristic temperature here is 1 million K.
